I need to do something like this to render html code in the head and can't remember the correct syntax. echo is not working

if (in_array($ezpage_id,explode(",",''))) { echo "<link type='text/css' href='test.html'>";}

When you say not working, what do you mean? If the condition is in some way true then the content identified would be pushed to the browser. So what *is* happening?

Nothing is happening. It isn't even picking up the condition on the EZ Page in the 'head' section.

If I view source it isn't even there in the head section that I can see.

Somewhat seams reasonable that it doesn't if the provided code as is was used. But two possibilities. Either the wrong file is being edited or the ezpages_id is anything other than 0 because of the explode on an empty quote.

It would be 60 but I haven't included it in the code here. So as not to confuse. It's not in the wrong place as if you look in tpl_main_page.php you will find this before the body which is the head section:

Ok, so what happens if you echo $ezpages_id on the page in question? I have a feeling that it is not yet defined at the point where it is being referenced/used.

The aim is to echo the html code on that page in the head section. Basically

<link type='text/css' href='test.html'>

needs to link to a duplicate of the page which is in another directory on the server. But it must echo in the head section.

[mc12345678]

That is understood. It does that by knowing something about the current page. The code provided uses $ezpages_id expecting it to be set to the value of 60 and when it is to display the html code. But the question is, does it or can it ever be equal to anything or as requested what does it equal at that point in processing?

Firstly the head section is for processing HTML elements and some are not for actual display on the selected page. In this case $ezpages_id 60

So

<link type='text/css' href='test.html'>

is a reference link to another page in the head section. Not like

<a href="test.html"></a>

which would display on the actual page.


'But the question is, does it or can it ever be equal to anything or as requested what does it equal at that point in processing?'

Explain better please as I don't understand fully. I think the answer is 'equal at that point in processing' but I am unsure .

[mc12345678]

You are at a point in trying to make something happen with code.

The code depends on:
1. $ezpages_id being a value that is in your comma separated string of ezpage ids.
2. If it is, then do something.
3. Nothing is seen to be happening.
4. So, the question is: at this point in processing the code, what is the value of $ezpages_id?

The way to see the value of $ezpages_id is to echo $ezpages_id.

So, on the line before your if statement. Add:

 echo '<!-- ezpages_id=' . (int)$ezpages_id . ' -->';

Then, load the page and view the source...
